Just got this from Marty Maloney regarding today's conference call with Brent:

Guys,

I sincerely apologize, but this is simply a case of bad timing/luck. Brent has just been called up to Charlotte today and will be on a flight at 3:00 p.m. I cannot apologize enough for any inconvenience these cancellations have caused. We’ll give me a day or so to get settled but hope to have him on by the end of the week.
